'Thisjshaft carries at itslower lend a. a gear 153 [which meshes through a change 7 gear With-a driving gear 70.

After passingbetween the lower rolls 1 11 a V "amt-1 12' the braidfpasses through a guide eye 160 in a guide bar 161 (Figure 4). The guide bar 161 is mounted to slide in a pair of arms 162 and 163 which project upwardly from a bracket 16 1 made fast to one'side of I the frame/ These arms 162 and .163 have journaled therein a shaft 165' which PI'OjGOtS beyondthe arm 163 and has fixed thereto a belt pulley 166. and carries a winding reel 167. A belt indicated at- 168 passes about this belt pulley 166, is crossed intermediate its lengthwand passes over a pulley 169 mounted to rotate with the roll 140. i

Provision is niade by which. thebar 161 is moved parallel-tothe shaft 165 in order to guidethe braid as it is Wound from one end to the other of the reel; For this purpose the bar 161 has in one face thereof a groove 170, this groovebeing in the form of an elongated loop extendinglengthwise of the barv and within this loop is fixed a series of pins 171 extending-outwardly from the face of the'bar, these pins being spaced to meshwith a 'pinion172- This pinion is carried by. a shaft 173 having its end 1.74 shaped't'o' fit within the groove 170 to be guided for traversing movement thereby.

The shaft 17 3 is fixed within the .end of a shaft 174?, these two shaft members constituting a transmission shaft which is jour- =naled in a yoke175, the arms 176 of which are mounted for rocking movement on the. drive shaft 165 between the arms'162 and 163. WVithin-this yoke the shaft 174?" has fixedijthereto a bevel gear 17 7 which meshes with a bevel pinion 178 fixed to the shaft 165; By thisconstruetion, as the shaft 165 1 is rotated-the' gear 1-77 is rotated, causing *a transverse movement in opposite direce tions of the bar '161by engagement of the "pins 171 with the teeth of the pinion 172.. As the bar 161 traverses, the gear 172 is held in engagementwiththe pins 171 by the end of the shaft 17-1engaging in the slot 170. As it reaches the .endof traverse 3 in one direction the portion 174 riding in" the" slot 170- causes the yoke 17 5 to tilt.

slightly about the shaft 165 as an axis and I'of' the series it starts thejtraverse ofthe bar 161jin the opposite direction. Q'Ihis is as. the pinion 172 rotatesabout the end pin illustrated in Figure 7 in which the positionsof'the'pinion172'with relation to the.

bar are *shown 'in' dotted lines when shaft 'l7 l engage's in upper andlowei reachesof the looped 'groove, these being the positions in which the bar is traversed in opposite mechanism for receiving strands in braided directions. By this construction the. braid is led evenly throughout the length of the reel 167 as it is wound thereon.

Having thus; described an embodiment of this invention it should be evident that many changes and modificationsfmight' be made therein "without departing from; its spirit for scope as defined bythe appended claims. 7 v
